Hi,

I start trying to solder brass valve for one of my garden hoses. The
problem is that the solder does not drawn into the joint. I follow the
instruction on Black & Decker home repair book. Solder melt at the edge
of the joint, then drop on the ground, and it does not suck into the
joint. I tried a couple of times, no solder ever drawn into the joint
and solder stays at the edge of joint, that is it. How am I going to
solder it correctly for brass valve? I heated the center of the valve
back and forth, nothing happened.

thx

In addition to what every one else said about cleaning and fluxing there is
one very important item. You must remove as much water as possible from the
pipe system. Any water in the pipe , for 2 or 3 feet, will draw away the
heat and you will not be able to get the pipe hot enough to melt/flow the
solder.

I was soldering a connection one time and couldn't completely turn the water
supply off. I had to open every faucet in the house to divert water away.
Luckily there were other faucets that were lower.

A small pump such as a drill powered pump may work to evacuate the pipe.
